Dianna M. Collier Warner

Dianna Collier Warner, 84, of Palm Beach Gardens, Florida, passed away peacefully in her sleep on April 19, 2026. Dianna was known for her elegance, intellectual curiosity, and deep appreciation for the finer things in life — whether expressed through food, literature, or travel. She lived a life rich in experience, creativity, and connection, leaving a lasting impression on all who knew her. She was born on Valentine’s Day, February 14, 1942, in Newark, New Jersey, to William and Bertha Meerwarth, who emigrated from Germany. She attended Pine Crest School in Fort Lauderdale, Florida and later graduated from Boston University. After college, Dianna moved to New York City, where she met her first husband, Oscar Collier. The two married and welcomed their only son, Christopher, before settling in Ridgewood, New Jersey. In Ridgewood, Dianna created a home centered around beauty and care, highlighted by a large backyard garden where she cultivated flowers and vegetables, a passion that remained with her throughout her life. More than a decade later, she relocated to South Florida where she forged meaningful relationships in the local community for more than 35 years. Dianna built a multifaceted and accomplished career. Early on, she worked in mergers and acquisitions at The Equitable. She later ran Collier Associates Literary Agency. She worked with aspiring writers and established authors to bring numerous books to life, with a particular focus on mystery writing. She was also the author of two cookbooks and served on the board of the Wine and Food Society. She was an avid reader of The New York Times, The Palm Beach Post, and Publisher’s Weekly. A passionate traveler, Dianna especially loved spending time in Europe, drawing inspiration from its culture, cuisine, and history. She had a distinctive and elegant sense of style and filled her homes with meaningful artifacts collected from around the world. She was also a lifelong animal lover, sharing her home with many beloved cats and dogs over the years. Dianna is predeceased by her spouses, Oscar Collier, William Vassilopoulos, and Fred Warner; her parents, William and Bertha Meerwarth; and her brother, Ralph (Lurenna) Meerwarth. Dianna is survived by her son, Christopher (Bre) Collier; her grandchildren, Caroline and Mary Collier; her step mother, Alice Meerwarth; her half brother, Thomas (Jill) Meerwarth; her half sister, Monica Meerwarth; her niece, Tracy (Scott) Meerwarth Pester; and her partner, David Watjen. Dianna will be remembered for her sophistication, her vivacious spirit, her love of books and food, and the beauty she brought into everyday life. She will be deeply missed by her family and all who had the privilege of knowing her. A visitation will take place on Thursday, May 7, 2026 from 2:00pm to 4:00pm with a service at 3:00pm at Taylor and Modeen Funeral Home. A private family burial will occur on the following day.
